AMERICAN INSTITUTE OF
STEEL CONSTRUCTION, INC
is a membership corporation representing the struc-
tural steel fabricating industry of the United States. It
was organized in 1921 and incorporated under the
laws of the State of New York in 1925. Among its
members are more than 244 of the nation's largest
and most responsible concerns which normally fabri-
cate and erect more than 85 per cent of the country's
annual tonnage for buildings, bridges, and other steel
structures. Supported entirely by membership dues,
it is a non-profit service organization, which all quali-
fied fabricators are invited to join.

The A. I. S. C. Standard Specification for the
Design. Fabrication and Erection of Structural
Steel for Buildings — Riveted. Bolted and Arc-
Welded Construction, is generally accepted
throughout the United States. The Specifica-

The purposes for which the Institute
and in furthering which its activities are conducted.
1. To further better methods — and to eliminate waste
in the design, fabrication, and erection of structural
-teel through a cooperative effort based upon simplifi-
cation and standardization.
2. To promote the growth of the fabricated structural
steel industry by expanding its possibilities and its
3. To establish and promote standards of ethical busi-
ness relations and to bring about uniform trade cus-
toms and usages within the industry, so that all who
deal with the industry may transact their business
with a minimum of misunderstanding.
4. To increase the fund of useful engineering knowl-
edge and to promote the science and the art of steel
construction through technical research: and to main-
tain a staff of district engineers to disseminate such
information to Architects, Engineers, and Public
Officials and to assist them in its application.
5. To collect and disseminate pertinent statistical in-
formation so that those engaged in the industry may
be able to conduct their business more efficiently.
6. To develop for the industry a better understanding
of the element- of cost through the use of the A. I. S. C.
standard system of cost accounting.
7. To foster, in general, the improvement of condi-
tions and business relationships within and without

This Code is the standard guide to approved
American practice in all dealings between the
purchaser and the fabricator of structured
steel for buildings and bridges. It \\ as revised
in December. 1946. It is frequently included
by reference in a purchase contract, assurin
that each party knows in advance what to
expect from the other. The Standard Proposal
Contract of the A. I. S. C. is printed with it.

Strength: Steel is the symbol of strength. It Fire Safety: Steel will not burn. There are
no structures more inherently fire-safe than

cause of its ability to withstand enormous the modern skyscraper, built with a steel

a well-deserved comparison.
Uniformity: Every process in making steel

Endurance: Steel structures are built for
the ages. The strength of steel is permanent
and does not deteriorate under service load-
Compactness: Structural steel provides the
maximum amount of usable interior space,
with a minimum of obstructions.
Speed: Steel-frame buildings have a record
for more rapid construction than any other
type of fire-safe structures. Members are fab-
ricated off the site and are delivered ready
to be placed in position.
